LUBRICATOR.

Specification of Letters Iatent.

Patented Dec. 25, 1906.

Application filed March 31. 1906. Serial No. 309,210.

' zens of the United States, have invented or discovered certain new and useful Improvements-inLubricators, of which improvements the following is a specification.

The invention described herein relates to certain improvements in lubricators, and has for its object a construction and combination of parts or elements whereby the same lubricator can be employed for feeding material,

such as grease, re uiring the applicationof heat to render it fluid, and also materials, such as oils, which hav sufficient fluidity wiifn cold to render the feeding thereof poss1 e.

The invention is hereinafter more fully described and claimed.

In the accompanying. drawings, forming a part of this specification, Figure l is a sectional elevation of our improved lubricator and connections. Figs. 2 and 3 are sections longitudinal of the fee nipple, showing the passages therethrough, the planes of section being indicated by the lines II II and III III, Fig. 1. Fig. 4 is a transverse section on a plane-indicated by the line IV IV, Fig. 1 and Fig. 5 is a sectional elevation illustrating a modification of our improvement.

In the practice of the invention the body or receptacle 1 is divided into two compartments or chambers 2 and 3 by a diaphragm 4. Nipples 5 and 6, having passages therethrough and provided with seats or sockets for the glass connecting-tube 7, are connected with the storage-chamber 3,- as shown in Fig. 1. The upper nipple 5 is formed with an oil or grease inlet port or opening which I is normally closed by a threaded plug 8. The

nipples 5 and 6 are so connected to the chamber-3 that the height of water, and conseuently the-quantity of oil or grease in the c amber 3, can be seen in the glass connect ing or indicating tube 7. As the glass indieating-tube 7 is at such a distance from the receptacle or body 1 that grease will harden therein in cold weather, a heating element in the form of a metal rod 9, carried by a plug 10, screwing into one of the nipples, is arranged to project into the glass tube. As

this rod has a metallic connection with the body 1, it will be heated by conduction and maintain the grease in the tube in a fluid condition.

The grease or oil contained in the chamber 3 is displaced and forced to the upper art of the chamber by water introduced t ough the tube or passage 1 1 which extends through the heating-chamber 2 the diaphra m 4, and preferably down to the lower end 0 the storage-chamber. This tube 11 is connected to a steam-supply pipe and the condensation flows through the tube to the grease or oil storage chamber. The rate of flow of convdensed water is regulated by a valve 12.

Steam is introduced into the heatingchamber 2 by the pipe or tube 13*, which, as shown in Fig. 5, may surround the tube 11, being connected thereto by ports 14; but as the heat of the steam in the tube 13 may be sufiicient to vaporize the water in the tube 11 and sufficient water will'not flow into the chamber 3 the tube 13 in Fig. 1 is arranged so as to prevent any material heating of the water in tube 11.

The oil or grease is forced by the water in the chamber 3 to the. upper part of said chamber and flows into the tube 15, which is connected to a nipple 16, preferably secured to the receptacle. The passage 17 in this nipple is connected to a nozzle 18, projecting up into the glass tube19, which has its ends arranged in seats or sockets in the nipple 16, and a nipple 20, secured to the receptacle 1 and connected to the heating-chamber 2. The flow of oil or grease is controlled by a valve 21 across the passage 17; The sight feed-tube 19 is connected to a passage 22 in the nipple 20, which also has a second passage 23 connected to the heating-chamber 2. The flow of fluids along these passages is con- ,trolled by valves 24 and 25. In order to clean the tube 19, a blow-off passage 26, having a valve 27, is formed in the nipple 16. Provision is made for cleaning the chamber 3 by blow-off passage 28, controlled by a valve 29. A check-valve 30 is arrangedat the lowerend of the tube 11 to prevent pressure in the chamber 2 forcing water or oil, or both, through said tube. As shown in Fig. 1, the ball 30 is arranged in a cage at the lower end of tube 11 and when shifted by pressure in chamber 3 will be forced against a seat and g'plvent water being forced up into tube 11. en free to move down, the ball rests upon ribs or points and will not prevent flow of fluid from tube 1 1 into chamber 3. As before stated, the oil or grease is charged into the chambers 3 through the nipples 5 and 6, and as soon as the chamber 3 1s properly charged the valve 12 is opened, allowing water from condensed steam to flow down into the chamber 3 under the proper pressure, which can be regulated by the valve 12. The oil or grease flows through the tube 15 to and through the nozzle 18, the rate of flow through the nozzle being regulated by the valve 21, which is generally adjusted so that the oil or rease escapes from the nozzle in the form of drops or globules.

When the lubricating material requires heating, steam is'introduced through the pipev 13 into the chamber 2, from which the steam escapes through the passage 23 in the nipple 20. When the lubricating material does not require heating, the valve 25 in passage 23 is closed, and the steam will condense and cool in the chamber 2.

We claim herein as our invention- 1. A lubricator having in combination a storage-chamber, means for introducing a displacing liquid into the storage-chamber, means for regulating the flow of oil from the storage-chamber, a heating-chamber arranged above the storage-chamber adjacent to the outlet therefrom andremote from the portion of the storage-chamber containing the displacing li uid, means for causing the flow of heating uid into the heating-chamber and an independent outlet therefrom.

2. A lubricator having in combination a receptacle having storage and heating chambers, a pipe or tube for introducing displacing li uid extending to or near to the lower end of the storage-chamber, an outlet-tube 'extending'from the portion of the storagechamber-adjacent to the heating-chamber, a

nozzle having a valve connection to the outlet-tube, a pipe for introducing heating medium mto the heating-chamber and a valveoutlet for the escape of the heating medium from said chamber.

3. A lubricator having in combination a receptacle having a horizontal diaphragm, a pipe or tube for introducing a displacing liquid into the lower or storage chamber extending through the diaphragm, an outlettube extending from a point in the storagechamber adjacent to the diaphragm, a nozzle having a valve connection to the outlet-pipe, and a pipe for introducing heatin medium to the chamber above the diaphragm, a chamber above the diaphragm having connections whereby a circulation of the heating medium through said chamber is eil'ected,

the outlet from said chamber being independent of the pipe supplying liquid to the storage-chamber.

1. A lubricator having in combination a receptacle having storage and heating chambers, a pipe extending through the heatingchamber for introducing a displacing liquid into the storage-chamber, nipples extending respectively from the storage and heating chambers, a tube extending from a passage in the lower nipple to a passage in the upper nipple, a nozzle extending from a valved passage in the lower ni ple into said tube, a pipe or tube extending rom the upper portion of the storage-chamber to said valved passage and a pipe for introducing a heating medium into the heating-chamber, said chamber havin an outlet independent of the supply-pipe.

n testimony whereof we have hereunto set our hands.
